Objective To investigate the effects of Xuezhikang (XZK) on carotid atherosclerosis plaque and blood lipids in patients with transient ischemic attack (TIA). Methods 65 patients with TIA were randomly divided into two groups: XZK group and control group.XZK group received XZK and Aspirin for 6 months, while the control group received Aspirin only. The intima-midia thickness (IMT) of carotid artery,the area of carotid atherosclerosis plaque, and levels of blood lipids, oxidized low density lipoprotein cholesterol (ox-LDL) and serum nitric oxide (NO) were measured before and after treatment.Incidence rate of cerebrovascular event in the two groups were compared in 6 months. Results After 6 months of treatment, the total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and ox-LDL concentrations decreased significantly in XZK group, however high density lipoprotein (HDL) and NO levels increased markedly (all P0.05).Conclusion It is shown that XZK not only effectively adjusts blood lipids, inhibits peroxide of lipids and protects vascular endothelial, but also regresses the atherosclerosis and stabilizes the plaque.

Renal artery embolization was induced experimentally in rabbits and microvascular changs were studiedangiographically, microangiographically and histopathologically. The results were as follows; 1. The mainmicroangiographic findings of renal artery embolization were arterial occlusion and collateral vessels arecharacterized by spiralling, dilatation, irregular lumen with abrupt caliber change, disoriented course andincreased number. 2. Collateral vessel formation was demonstrated in all cases of renal artery embolization bymicroangiography. 3. Recanalization of embolized vessels was better visualized by renal angiography thanmicorangiography. It was considered that microangiography is a valuable method for the observation ofmicrovascular changes in renal artery embolization and other renal diseases.

Objective To explore some characters of auditory steady-state responses (ASSR) to multiple simultaneous stimuli in a sample of normal-hearing adults.Methods The ASSR to multiple simultaneous stimuli were recorded in a sample of 32 normal-hearing adults (64 ears). Simultaneous carrier tones (0.5, 1, 2 and 4 kHz), modulated in amplitude at different rate of 77, 85,93, 101 Hz for left ear and 79, 87, 95, 103 Hz for right ear, were presented binaurally by the insert phones. For each subject the response thresholds (RTHs) at 0.5, 1, 2 and 4 kHz were determined automatically and compared with the corresponding behavioral thresholds (BTHs).Results ①In the normal-hearing adults, RTHs were on average between 7～19 dB above the BTHs.②2-way repeated measures ANOVA (ear?carrier frequencies) showed significant main effect between carrier frequencies on RTH ( F =31.254; ? 3,179; P =0.000). Post Hoc analysis indicated that this effect was due to the highest threshold found at 0.5 kHz. The test showed no significant difference of threshold between left ear and right ear ( F =1.942; ? 1,179; P =0.165). ③Taking 60 dB SPL as analysis level, 2-way repeated measures ANOVA (gender?carrier frequencies) revealed significant difference of amplitude between male and female( F =16.490; ? 1,175; P =0.000); and difference of amplitude between carrier frequencies ( F =2.948; ?3, 175; P =0.034).④The average testing time was 61 minutes for male and 69 minutes for female. Independent t-test showed statistical significance within sex.⑤Two- way ANOVA (state?frequency)showed that background EEG noise were significantly higher in awake than that in sleep ( F =152.511; P =0.000). There were no appreciable significance in background noise among frequencies. Conclusion The ASSR to multiple simultaneous stimuli was proven to be a frequency specific, objective and valid technique for threshold estimation at least for normal-hearing adults. Issues concern ing clinical use were discussed.

ObjectiveTo analyze the relative influential factors of hearing rehabilitation of the deafened children with multichannel cochlear implant. Methods42 prelingually deafened children who accepted multichannel cochlear implant were evaluated with their hearing ability, hearing thresholds and talent level, while their family and usage of the multichannel cochlear were investigated. Results and ConclusionThe result shows that the factors influencing the hearing rehabilitation are the occupations of the parents, income of the family, the time between diagnosing deaf and the operation, the time after the cochlear implant operation and the talent level. The results of the logistic regression show that the deafened children can gain their hearing developing rapidly if they living in a family with high income, their mothers have accepted more education, and they accepted longer time of continuing hearing-aid, etc.

PURPOSE: To describe the radiological differences between tuberculous(TBB) and non-tuberculous bronchiectasis(NTBB). MATERIALS AND METHODS: Chest radiographs(n=62), bronchograms(n=18), and CT scans(n=52) of 37 patients with TBB and 25 patients with NTBB were reviewed retrospectively. Diagnostic basis for TBB were positive sputum AFB with or without history of anti-tuberculous chemotherapy(n=35), and radiological findings of pulmonary tuberculosis (n=2). Four of NTBB had a history of severe respiratory tract infection in childhood. RESULTS: Air-fluid levels on chest radiographs were seen in 2% of TBB, and 20% of NTBB. On bronchograms, all patients with TBB had combined focal bronchostenosis, whereas patients with NTBB had tubular(50%), cystic(17%), or mixed(33%) pattern of dilatation without stenosis. On CT scans, focal emphysema was seen in 86% of the patients with TBB, and 38% of the patients with NTBB. Peribronchiolar infiltration were seen in 78% and 44% of patients with TBB and NTBB, retrospectively. CONCLUSION: Basic radiological difference between TBB and NTBB was that the former had coexistent sten.

Mixed Mullerian tumors are rate uterine malignancy and occur primarily in postmenopausal women. We have experienced three case of pathologically proven mixed Mullerian tumor. Two cases had prior history of pelvic irradiation for uterine cervical carcinoma. We suggest that mixed Mullerian tumor should be suspected when an enlarged uterus with polypoid masses in the uterine cavity are initially observed in postmenopausal women who had history of pelvic irradiation.

Between May 1984 and December 1989, 57 consecutive renal injury patients (55 with blunt and 2 with penetrating trauma) were evaluated. The injuries in this series were classified as contusion, laceration, rupture and pedicle injuries ac cording to Cass`s classification. Among 57 patients, 30 patients were classified into contusion, 14 patients laceration, 10 patient rupture and 3 patients pedicle injury. All contusion and laceration injuries were treated conservatively, 8 patients with rupture were managed conservatively and 2 patients with rupture were managed operatively (1 case: nephrectomy, 1 case: renorraphy). Among 3 patients with pedicle injury. 2 patients performed nephrectomy and 1 patients was died. Among 57 patients, comlications were developed in 5 patients (urinoma in 1, UPJ obstruction in 1. hematoma in bladder in 1, renal infection in 2) The management of comlications were renorraphy in l and conservatively in 4.
